The letters represent-the different parts of saidmachine.

ll M N is the main suppor-ting-fran1e,which is constructed in thecomnion way. A is the main drivingavheel K the shaft, and F F the armsof sarne. .ifi'is'a cam. attached-to the inner periphery of thedrivingwheel. (.l is a .(l'OSS-lltflli. is a pitnian. (t is a key. Eis

a stirrup. (l G are s rings. H is a hub or fulcrum. J J" are bolts andnuts. I 1" are cams upon the underside of the cross-head (J, as in Figs.4 and 5. P is a nut. q is awasher. R is a bolt. 8 is a recess in theedge of the pitman I). 0 is a hole infi'the end of the said pit-man,where thesickle-bar is attached.

Having named theseveral parts of the said machine, I. will now explainits operation and construction as best I can.

The frame flli M N of the said machine is made in the usual way,thedriving-wheelA also, with the exception that the arms F F thereof areattached to the side of the rim. 'Upon the inner periphery of the saidwheel I place azigzag way or cam, B, sometimes whole and at other timesin sections. I pre- .l'er the sections, for the reason that it is moreveasily repaired. In front of the said wheel and lnatween thecross-beams L L, I place the stirrup 1*}, and fasten it to the saidbeams with the bolts and nuts j j; and itis obvious that the saidstirrup can easily be tilted toward the rear of the said machine, ortoward the front, as may he rm uired, which will be more fully explainedhereinafter. New, this said stirrup is peculiarly (oust nueted with abase and sides or cars. .At right angles with. the sanic, upon the uppersurface of the said'base, isa hub or PATENT. OFFICE. a

-':- Specification thrming partot' Letters Patent No. 35,923,' datedJuly 22, 1862.

flll(..llllll,ll,lfllld the pitnian D hangs upon this said hub, the holethrough the said pitinan corresponding in sizewith the said-hub, and theheight of the said. hub corresponds also with the thickness of the saidpitinan. Now, I insert a bolt, B, through the center of the said hubfrom the bottom of the said stirrup. Now, when the said pitinan is inits proper place, as described, and as seen in Fig; 6, It place awasher, q, upon the top of tl-e said hub, (the'said bolt passing throughthe center of it also,) and then I put the nut p upon the said bolt andscrew it down upon the top-of the said washer, which said washer liesupon the top of the said huh, and in this avay permanently secure thesaid pitman in its place; but it will be understood that the said pitmanis sul'iiciently relieved to admit of free action.

It will be seen in Fig. 2 that the fulcrum of the said pit-man isimmediately in front of the said driving-wheel; hence the necessity ofcrooking the rear end to pass by the side of the said whee]. Upon therear end of this said pitman I place the cross-head C, and fasten itthere with the key a, as seen in Fig.

8, a mortise being in the end of the saidcrosshead, corresponding insize with the size of the end of the said pitn -an. On the inner edge ofthe said pitman is a recess or boxing, 8, into which the said cross-headis placed, and is permanently held there when the said key is insertedinto its proper place, as seen in Fi g. 3. The said cross-head isconstructed with cams I l. on the under side thereof, as seen in Figs. 4and 5, corresponding with the angle of the said-cam upon the innerperiplr cry of the driving-wheel. It is manifest, therefore, that whenthe said cross-head 'is properly adjusted to the said cam on the saidwheel and the said wheel set in motion the said cross-head, andconsequently said pit-man,

will Vibrate equally with the angles or radius ot' the said cam. Thesaid pitman being pivoted at ornear the middle thereof it is alsomanifest that the other or front end thereof will also vibrate in thesame proportion with the rear end. The sickle or cutting apparatus, being attached to the frontend of the said pitman at the point 0, as seenin Fig. 3, is also set in motion when the machine moves.

The springs G- G" are attached to the sides or ears of the said stirrupE, and extend forward in the plane of the said pitman, .sufiicie'ntlyinclined toward the same to bring them in contact with the sides thereofat or near the end. The use of the said springs is to soften the actionofthe said cross-head upon the said cam and to regulate the motion ofthe entire machine The object of hinging. the said stirrup upon the saidbolts j j (as before stated,) is to enable meto throw the machine in andout of gear, for it is clearly manifest that when I tilt it. toward thefront the rear end of the said pitman will raise and-consequently detachthe saidcross-head from the said cam of the said whee] and thereforestop, the'motion of the said cutting apparatus; and when I reverse theposition of the said stirrup by tilting it toward the rear of the saidmachine it brings the said crosshead in contact with the said cam again,and thereby sets the cutting again in motion, and vice Versa.

What Icl-aim, and desire to secure by Letters Patent, .is

1. The adjustable hinged stirrup E, in com- I bination with the pitmanD, when constructed and arranged in relation to each other as specified,and for the purposes described.

2. The springs G G in combination with the said stirrup E and the pitmanD, when the several parts are constructed, arranged, and operate in themanner and for the purposes speified.

3. The cross-head O, in combination with the said pitman and the maindriving-wheel A,when the several parts are constructed, arranged, andoperate in the manner and for the purposes specified.
